Specification of Letters Patent.

Application filed August 29, 1906. Serial No 332.526

To all whom it may concern:

Be it known that I, VrNcEN I. MoVoY, of Pensacola, in the county of Escambia and i State of Florida, have invented certain new and useful Improvements in Sap-Collectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of this invention areto simplify and cheapen the construction of a sapcollector, to enable the device to be readily and easily secured to and detached from a tree, and to facilitate the attachment and release of the sap-receptacle. i

Theinvention is particularly designed as an improvement upon the form of sap-collector shown in Letters Patent No. 833,081, issued October 9, 1906, and is adapted for carrying out the process embraced by Letters Patent No. 832,405, issued October 2, 1906.

The invention will be hereinafter fully set claims.

In the accompanying drawings, Figure 1 is a vertical sectional view, a portion of the tree being indicated. Fig. 2 is an end view of the spout. Figs. 3 and 4 are opposite end views of the sap-receptacle. Fig. 5 is an exterior view at right angles to Fig. 1. Fig. 6 shows a slight modification of the spout-engaging end of the receptacle. Fig. 7 is a face view of the tree-engaging end of the spout, the receptacle-engaging end of the latter being modified to adapt itself to a modified formv of cup shown in side elevation in Fig. 8. Fig, 9 is a lower end view of the spout, and Fig. 10 an. upper end view of the receptacle shown, respectively, in Figs. 7 and 8.

Referring to the drawings, 1 designates a spout, shown as of elbow form, provided at its upper end with a large circular flange 2 for fitting tight against the edge of a bore 3 cut in a tree. From the axial center of flange 2 above the end of the spout projects a post 4, threaded to engage a second bore formed centrally of the main bore. A suitable tool may form both bores at the same time. This post holds the flange 2 air-tight 3, thereby hermetically sealing the latter. The lower end of the spout terminates in a laterall sealingl flange 5, preferably beveled on its under face,

and a depending flange 6, which latter is provided with opposite diametrically arranged lugs 7.

8 is the cup or` receptacle, the upper end of i which is'beveled to conform to flange 5 and is provided at said end with diametrically disposed lugs 9, similar inform and arrangement to but preferably slightly longer than lugs 7. These lugs 9 are shown in Figs. 1 and 3 as being formed in the upper bell or flared end of the cup but, as shown in Fig. 6, the upper end of the latter need not be flared. The lugs 9 are shown as beveled on their lower faces, so that when the cup is positioned withits lugs in the spaces between the lugs 7 of the spout and is turned axially its beveled end will be drawn by the cam action of the two sets of lugs tight up lagainst the asket 10, interposed between the cup and lange 5. In this way the cup is hermetically sealed to the lower end of the spout. By giving a reverse quarter-revolution to the cup the lugs thereon willmove out of engagement with the lugs on the spout and register with the intervening spaces, thus allowing the cup to be detached for discharging sap therefrom. Y To enable the cup to be tightly secured in position and to aid in the removal thereof, its ower end is hexagonal or of other polygonal formation, as shown at 12, so that by the application of a suitable wrench, such as is shown at 13 in Fig. 7, the cup may be readily manipulated. For the same reason I form onl the under side of the spout a lug 14, with which the hooked end of the wrench or other spanning-tool may be caused to engage, so as to permit of the screwing or unscrewing of post 4. (See Fig. 7.)

In the spout, preferably on the upper face.

thereof, is formed an opening 15, through which air may be exhausted for the creation of a vacuum within the extractor, such opening being normally closed rubber or other suitable material formed with openings at its ends for fitting over lugs 17, preferably cast integral with the spout. Although I ordinarily employ artificial means for exhausting the air to create a vacuum, yet with the opening closed by the rubber and the parts hermetically ,sealed changes in temperature from a warm day to a cold night by a section 16 ofl IOO will contract the confined air and create aV partial vacuum.

As evidencing the fact that the receptacle may be secured by various means directly to the spout I have shown the former in Fig. 8 as having the lugs 9a on its exterior, while the coperating lugs 5EL on the spout are formed on the inner face of a flange 5b, depending from the horizontal flange 5C. v

An additional intersecting bore, exposing a greater number of pores to the action of the vacuum, is indicated at 18, Fig. l.

I claim as my invention` l. A sap-collector comprising a spout adapted for attachment to a tree, having at its outer end a lateral flange, and oppositelydisposed lugs, and a cup having at its upper end oppositely-disposed lugs designed to eooperate with the lugs of the spout, the upper end of said cup fitting against the under side of said flange when its lugs are in engagement with the lugs on the spout.

2. A sap -collector comprising a spout adapted for attachment to a tree, having at its outer end a lateral flange, oppositely-disposed lugs, and a depending flange, and a cup or receptacle designed to fit over said depending flange and having oppositely-disposed lugs for engaging the lugs on the spout, one set of lugs being beveled so that the cup will be held by a cam action with its upper edge against said lateral flange.

3.V A sap-collector comprising a spout having at its outer end a laterally-extended flange beveled on its under face, and a depending flange having oppositely-extended lugs, a cup or receptacle beveled at its upper end to conform to the bevel of said flange, a gasket interposed between said cup and said flange, and lugs on said cup for coperating with the lugs of the spout.

4. A sap-collector comprising a spout having at its lower end a lateral flange and oppositely-.disposed lugs, and a cup having at its upper end lugs for coperating with the lugs of the spout, said cup being designed to fit against said flange, the lower end of said cup being of hexagonal or other polygonal shape.

5. A sap-collector comprising a curved spout having at its upper end a threaded portion designed. to be secured to a tree, a receptaele detachably held to the lower end of such spout, and a lug on the spout extended longitudinally of the latter and designed to be engaged by a tool or spanner for effecting the turning of the spout.

6. A lsap-collector comprising a spout having at its upper end a flange extending therefrom, a threaded post projecting centrally from said flange, said post being designed to hold said flange hermetically against the edge of a bore in a tree, and a cup detachably secured to the outer end of' said spout.

`7. A sap-collector comprising a spout having an air-vent therein, and a section of nonporous material on the outside of said spout and designed to be detachably secured thereto lfor closing said vent.

8. A sap-collector comprising a spout having an air-vent therein, lugs formed integral with said spout adjacent to said vent, and a band fitted over said vent having holes to accommodate said lugs.

9. A sap-collector comprising a spout having at its upper end a circular flange, a threaded post projecting from said flange and designed to hold the latter against a bore in a tree, said spout having at its outer end oppositely-disposed lugs and a sealing-l lange and a cup having oppositely-disposed lugs for coperating with the lugs of the spout, said cup being held air-tight against said sealingflange of the spout when the two sets of lugs are turned into axial engagement with each other.

In testimony whereof I have signed this specification in the presence of two subscribmg witnesses.
